Limiting factors for encoding and transcoding.

I do quite a lot of encoding and transcoding on my pc (specs in sig) and it takes a while to change stuff to dvd format from VCD or Divx. Using nero7 it takes;

1.36gb divx to dvd = 1hour 12mins
2x700mb VCD to dvd = 3hours 50mins

Thats a long time for both really. and id like to cut down the time it takes to transcode vcd's to dvd. Any ideas? is Raid 0 the solution?

the vcd's cd1 is 1hour 2mins and cd2 is 52mins
the divx is 102mins thats loads better quality then the vcd tho.

does nero take advantage of dc cpu's? i dought a 3.8ghz (im assuming thats the fastest singlecore they make(bar the over priced EE chips) would make much of a diff

Using nero 7 to encode a 1.37gb file takes about 42 mins, using a Pentium D 830, it seems to take advantage of both cores as according to task manager its using 97%.

If its the 660 in your sig that your using, then its only hyperthreading, which is pretty useless for encoding, you need true dual core.

i know the diff between logical and physical cores

1.3gb = 102mins
2x700 - 124mins

time to encode

1.36gb divx to dvd = 1hour 12mins
2x700mb VCD to dvd = 3hours 50mins

Somethings wrong with that time for vcd to dvd it shouldnt be anywhere near that amount of time. The vcd is only 114mins long, it should be roughly the same length as the divx one, not more than 3x longer. What program are you using because with a 3.8ghz cpu you should be getting less than a 1:1 encoding ratio, I would have thought that you'd be getting 1:0.75 at the worst. Unless your using two pass encoding?

Try svcd2dvd, is one of the best programs out there for dvd conversion, it might be the software that your using.

3.6ghz cpu.
Nero7
Two pass encoding is on yes. Shall i turn this off - will it decrease the image quality a lot? Im pretty fussy on how a film/programs looks(in terms of picture quality), or i wont watch it.

Going to try the programs suggested
